Abstract : This thesis extends the development of the Advanced Airland Research Model (ALARM), a research effort at the Naval Postgraduate School (NPS), in the areas of urban terrain representation and urban mission planning. The growing proportion of dismounted infantry forces in the U.S. Army and the increased urbanization of Europe requires having a means at hand for studying the use of dismounted infantry in urban combat. The feasibility of using networks to model urban terrain and sequence the activities comprising an urban mission are demonstrated. A division scenario is developed that links brigade and battalion terrain networks. A template for an urban defense mission is developed and demonstrates the use of networks for stimulating mission planning in built-up areas. An outline is provided for linking multi-level terrain and mission networks into one planning model.
